APA Lab Report Format (7th Edition): Sections, Headings and Example

Most students learn APA lab report format from a handout, not from APA, so an APA format for a lab report mixes APA rules with that handout. APA Style's sample papers page offers a student paper and a professional paper, plus student templates for several kinds of assignments, including a quantitative study. It doesn't list a lab report template. So a lab report is a science assignment written in APA style, and your instructor decides the details of the APA lab report format you follow.

What is fixed and what is common practice

APA 7 does set the rules behind APA lab report formatting: title page, heading levels, tables, numbers, statistics, citations and the reference list. The sections in a lab report APA format example (introduction, method, results and discussion) are common practice in the sciences, so follow your course handout where it differs.

Where the tool fits

Build the first page of your APA lab report format with the APA title page generator, then use the citation tool above, or the APA Citation Machine, for the reference list. For margins, fonts and spacing, our APA format guidelines cover the whole paper, so this guide doesn't repeat them.

APA's order of pages page lists the pieces of a student paper in this sequence: title page, abstract, text, references, footnotes, tables, figures and appendices. It adds that student papers generally don't include an abstract unless requested. Here is how a typical APA format for a lab report fills that order, and the same list works as a lab report APA format example outline:

1. Title page. Title, your name, affiliation, course, instructor and date.
2. Abstract (if required). A short summary on page 2, with keywords if asked.
3. Introduction. Background, the question and your hypothesis. It opens the text under the paper's title.
4. Method. Participants, materials and procedure.
5. Results. What you found, with statistics, tables and figures.
6. Discussion. What the results mean, limits and next steps.
7. References. Every source you cited.
8. Appendices. Raw data, instructions or other long material, if your instructor wants them.

Your course may differ

Some chemistry and biology courses change the APA format for a lab report, asking for a purpose, a list of equipment, observations and calculations instead. In that case keep the section names your instructor gives you and use APA for everything else: headings, numbers, citations and references.

APA lab report formatting relies on APA's five heading levels. Most reports need only the first two or three levels.

No “Introduction” heading

APA says not to add an “Introduction” heading at the start of a paper: the title, repeated at the top of the first page of text, serves as the Level 1 heading. Place Method, Results and Discussion at Level 1, and Participants, Materials and Procedure at Level 2. That mapping is common practice, not an APA rule for lab reports, so match your handout.

Use only the levels you need in APA lab report formatting

Most lab reports stop at Level 2. Add a deeper level only when a subsection really needs its own parts.

APA's student title page has seven elements. Center the paper title in bold, three to four lines down the page. Then, each on its own double-spaced line, add your name, your department and school, the course number and name, your instructor and the due date. Put the page number 1 at the top right. Student papers don't include a running head unless your instructor or school asks for one.

The abstract, only if you're asked

The APA abstract and keywords guide sets the format: the label “Abstract” centered and bold on page 2, then a single double-spaced paragraph with no indent. The maximum is 250 words unless your instructor says otherwise.

Keywords

In APA format for a lab report, if you add keywords, put them one line below the abstract after an italic “Keywords:” label, indented like a paragraph. Use three to five, lowercase except for proper nouns, separated by commas with no ending punctuation.

Introduction

In a lab report APA format example, the introduction moves from the broad topic to your specific question. Cite the studies you build on, describe the gap, and end with your hypothesis. Write about specific earlier studies in the past tense: Roediger and Karpicke (2006) found… and use the present perfect for general research activity, as in researchers have studied this effect.

Method: participants

In APA lab report formatting, say who took part and how many. APA's numerals page says to use numerals for 10 and above and words for zero through nine, so write the study had 40 participants and three groups.

Method: materials

List the tools, surveys or apparatus you used. In a chemistry lab, this is where measured amounts go, with numerals before units such as 5 mL.

Method: procedure

Describe what happened, in order, in the past tense.

In an APA lab report format example, the results section reports what you found, in the past tense, without interpreting it. APA's numbers and statistics guide sets these rules for statistics:

• Use italics for letters that are statistical symbols, such as M, SD, t, p and N. Greek letters stay upright.
• Put a space before and after a mathematical operator: M = 7.7.
• Don't define common symbols such as M, SD, F, t, df and p.
• Report exact p values to two or three decimals (p = .006), and write p < .001 in text for smaller values.
• Omit the zero before the decimal when a statistic can't exceed 1, such as a p value or correlation; include it when it can.
• Give means and standard deviations on integer-scale data to one decimal and most other statistics to two.

Tables and figures

In APA lab report formatting, use a table when readers need to compare several numbers, and don't repeat the same statistics in the text and a table. APA's table page puts the number in bold above the title, the title in italic title case, notes below, and no vertical borders. Our APA table format guide shows every step, including notes and placement.

Refer to each table by number in your text, as in Table 1 shows the mean scores.

Discussion

In APA format for a lab report, start with your main finding and say whether it supported your hypothesis. Then compare it with the studies from your introduction and admit limits such as sample size. APA's verb tense guidance puts implications, conclusions, limitations and future directions in the present tense: The results indicate… Future research should explore…

References

Start the list on a new page, titled “References” in bold and centered. APA's reference list setup page asks for alphabetical order, a 0.5-inch hanging indent and double spacing. Every in-text citation needs an entry and every entry needs a citation. For multi-author sources, see our guide to citing two authors in APA.

Appendices

Long material in an APA lab report format example, such as the full stimulus list or raw data goes in an appendix after the references, if your instructor requests one.

Tense is where many lab reports slip, even with good APA lab report formatting elsewhere. APA's verb tense page lists past tense for your method and results in any APA lab report format, such as Participants took a survey or Scores decreased, and for specific studies in a literature review. It lists the present tense for discussing implications and for conclusions, limitations and future directions.

Keep a paragraph consistent

APA's page also says to keep one verb tense consistent within a paragraph and across adjacent paragraphs.

Here is a complete outline, an example lab report with APA 7 format that you can adapt. The experiment, student and numbers are invented for this guide; only the 2006 article is real. Use it as a model for APA lab report formatting.

Title page. Retrieval Practice and Vocabulary Recall: A Classroom Experiment. Maya Johnson, Department of Psychology, Lakeview Community College, PSYC 101: Introduction to Psychology, Dr. Alvarez, October 26, 2026.

Abstract (if required). Forty-eight students studied 20 nouns, then took a practice test or restudied. Two days later, the practice-test group recalled more words. Keywords: retrieval practice, memory, vocabulary.

Retrieval Practice and Vocabulary Recall: A Classroom Experiment (the title again, as the first heading of the text)

The introduction reviews Roediger and Karpicke (2006), states the gap, and ends with the hypothesis.

Method (Level 1): Participants (Level 2) lists 48 students; Materials describes the 20-noun list; Procedure describes 5 min of study, the practice test or restudy, and the final test two days later.

Results (Level 1): the t test above, plus Table 1.

Discussion (Level 1): the main finding, its meaning, limits such as one class and one list of words, and ideas for future research.

References (new page): the Roediger and Karpicke entry shown in the examples, with a hanging indent.

Check for these slips in APA lab report formatting before you submit:

• Treating the section list as an APA rule. APA has no lab report template; follow your handout where it differs.
• An “Introduction” heading. The title does that job.
• Statistics in plain text. Italicize M, SD, t and p.
• A zero before p. Write p = .006, not p = 0.006.
• Wrong tense. Past for method and results, present for implications.
• Vertical lines in a table. APA tables use horizontal rules only.
• Unnumbered tables. Number each one and mention it in the text.
• Citations without references. Match every in-text citation to an entry.

Final check

As a last step for your APA lab report format, run the finished reference list through the APA citation generator, and compare every table with the numbers in your text. For more APA help, browse the student guides hub, or see our guide to how to cite a quote in APA.
